-current kernel can boot with your patch. Thank you.

I add aprint_normal() at l->l_stat = LSONPROC in kern_synch.c, kern_softint.c,
kern_sleepq.c, kern_lwp.c and make kernel and boot several times.
Panic occured after kern_softint.c:softint_dispatch().

I add KASSERT(1==0) at softint_dispatch(), I got following trace.
